Rupert Murdoch’s newspaper publishing stable, News UK, is being sued for more than £500,000 for alleged age discrimination by one of The Sun newspaper’s biggest showbiz names.

Dave Hogan, 53, one of Britain’s best-known celebrity photographers, is due to appear at an employment tribunal in east London in July after initiating proceedings against News UK in the wake of the sudden termination of his contract after 33 years continuously working for the tabloid.
